TOP CAI! FOR SUGAR-MILL HOUSINGS.

Application filed September 23, 1919.

To all whom it may concern.

Be it known that I, Jnssr. I. BOYER, a citizen of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new and vide a cap that will permit of easy removal from the housing, and more particularly one that may be removed without the necessity of first removing the king bolts.

The invention is intended as an improvement on the construction described and illustrated in Letters Patent No. 976,144, issued to me under date of November 22, 1910.

In the above noted patent, the removal of the top cap could only be accomplished after the king bolts were removed, and this operation is tedious and laborious, and it is to overcome this objection that I have devised the present form of top cap.

In my present invention, the king bolts are provided with supports, independent of the cap, and the cap is secured by means of keys, whereby all that is necessary to remove the cap is to first remove the keys holding it, when it will be free to be lifted from its position on the housing.

The invention is more fully described in the following specification and clearly illustrated in the accompanying drawing, in which Figure 1 is a front elevational view, onehalf of which is in section, of the upper extremity of a housing and its cap, indicating also the relative position of the top roll.

Fig. 2 is a plan View of the cap in posi- The numeral 1 designates the upper extremity of a housing for the rolls and bearings, 2 designates the upper roll and 3 the a top bearing therefor.

The numeral 4 designates the supports for the king bolts 5 which pass through the supports and through the cap, and which are provided with the usual nuts 6.

Serial No. 325,790.

The numeral 7 designates the capwhich is formed with two substantially rectangular openings extending therethrough, one on either side of the verticalcenter, and which fit over the supports for the king bolts, and permit the cap to rest upon the upper edge of the housing.

The numeral 9 designates a pair of keys. adapted to fit in key ways 10, one-half of which key ways is formed in the cap and the other half in the king bolt supports, so that, when the cap is in position as shown, the keys will securely hold the parts in their relatively proper positions.

When, therefore, it is desired to remove the cap, for the purpose of removing the top roll and its top bearings, indicated by the numerals 2. and 3, it will be necessary to merely remove the two keys and the cap may be lifted, vertically from its position, thus allowing access to the said top roll and bearings.

The keys are preferably of uniform thickness and width, and are provided with nuts 12 for securing them against accidental removal.

It will be noted therefore, that by means of this simple structure, I am able to easily and rapidly remove the top cap, the upper roll and the upper bearings. without interfering in any manner with the king bolts, and that while the removal of these parts is being accomplished, the entire structure, other thanthe parts named, will remain intact.

Having thus described my invention, I

posed keys adapted to secure the cap to the said supports. I

2. In a top cap for sugar mill housings, a cap member formed with two vertical openings and two horizontal key ways across the path of said vertical openings, a pair of king bolts for engagement with the housing,

supports for the king bolts, said supports fitting snugly in said vertical. openings in the cap, horizontal key Ways in said supports a'claptcl' to register with the key ways in th ca and keys for seouririg the c ip to the supports.

3. In a device of the character described.

2 pair of king bolts, supports for said bolts, a removable cap adapted to fit over said supports, and a pair of keys adapted to en- 10 gage both the cap and the supports to hold the cap in position thereon.

In testimony whereof I a-fiix my signature.

JESSE I. BOYER.
